proved device whichis describedherewith. C i chargegport 7 whichmay be o f anyidesired s iz 1 While a dispensing-container capable or applyand shape and located in any desiredpartof the 110 y hinged end. of the carton. This port is preferably' near a corner of the carton, however, as shown in the drawings, and it preferably communioates with the'interior of the carton through a non-dumping manifold, which will be described hereinbelow. Air is drawn in and air and dust are discharged through the port and manifold by the action of the bellows. V r

Whether or not the discharge port '7 and the manifold communicating therewith are employed, a verticallyv discharging port 9 is provided in one side of the container. In the pre'-. ,ferred'instance, when ports 7'and 9 are both provided, the port 9 is in theupper side of the box I hear the hinged end when the port 7 is in its preferred position in an upper corner of thehinged end, as shown. It is also preferable to have theport 9 in the oppositeside section from port7: that is, when port 7 is in sectionl, port 9 is preferably in section 2.

This vertically discharging port' 9 makes 'it possible to apply heavy clouds of dust of low velocity to the underside of low-growing foliage and the like. The port opens directly from the interiorof the container and may be located in any side thereof perpendicular to the hinged end,

which makes it'adapted to discharge dust upwards when the greatest dimension of the container is ina substantially horizontalplane.

The location of port 9 in proximity toport '7,

the manner shown, is usually preferable, how-' ever, as thecontainer is then adaptedto be held and operated in the same manner for any dusting purpose. r As inthe case of port venient to have both ports substantially cir f cular and of substantiallythe same size, such as 40 frorh' inch to 1 inch in. diameter, for example;

1 Th'e'mo'st desirable size,- of course, depends onthe size of the container and the nature of thematerial tobe dispensed thereby. When two ports are provided and both are of substantially the same size, an interchangeable cork or other stoppering device can be employed to close off whicheverport'is notinus'e in any dusting operation. Whether the two ports '7 and 9 are provided,

. or only one of them, it is sometimes convenient to V present instance.

maybe fastened to'the seal orwrapping before one of the side sections.

provide a separate filling port .10, as indicated by dotted lines in the drawings. This filling port may be in either sidesection ofthe con-Y Thebellows'isthen closed, bringing the two sections of the container into parallel relation as shown in Fig. 2. They are retained in this position by means of a strip or seal of adhesive material ll of any desired width which extends part or all the way around the container. In the drawings, the strip 11 is shown as equal in width to the thickness of the closed container to which it'iS applied on three sides.

'A rip cord 12 is preferably laid around the' dividing line between-the 'two sections prior to application ofthe seal '11, with oneend of the cord extending beyondthe seal, as shown in'the Alternatively, the rip cord 7 7, the port 9 may be of any desired size and shape, but it is usually conthe latter, is applied to the container, in which case the rip cord and seal are simultaneously ap-- plied in a single operation. The rip cord may extend completely around the container or only part wayaround as, for instance, along one side and across the end opposite the hinge.

In assembling the container, a bellows of strongpaper. or other suitable material is prepared as described in my copencling applications referred to'hereinabove. I prefer to employ the improved type of bellows described in my ap-- plication No. 572,918. Such a bellows is prepared froma polygonal blank consisting of an end sectionand' twosimilar side sections with or without end tabs which fold down. over the hinged "end 'of the container. This blank is creased'along its center line from end to end and may or may not be provided with reinforcing strips, stifieners and/or a protective coating as described in the said applications.

Before applying the bellows, the two side sections 1 and 2 are hinged together along'the edges 3 with a non-dumping manifold 15 fastened into section 1, ifa manifold and horizontal discharge port 7 are to be provided. Ports '7 and 9, and 10 if provided, are punched before hinging 'the'two sections together; The manifold 15 maybe of any suitable type, such asone of the types'dee scribed in my pending applicationsor the improved type. described hereinbelow,'and it com- 195 municates with the dischargeport 7, as shown inFignl. While the non-dumping 'manifold may be omitted from'containers intended to operate exclusively by. discharging ldusts upward thro-ugh'llo the port 9, itisan essentialfeatureofthe com-. bination or general utility dusting carton which is the preferred embodiment of myinvention. The function of the manifold is to prevent dumping or direct discharge through the port 7. of the in= secticide, fungicide, orother' pulverulent material with which the'carton isfilled, especiallywhen dusting in a downward direction. A

Generally speaking, the manifold which I prefer to employ. consists of an outer casing which is usually rectangular and-of substantiallythe same length and depth as the side section of the container with which it is to be employed,zthe space'within the casing-being divided. into-two substantially parallel passages by'i means of a middle lamella. .One. of these passages communicates with the discharge port 77' and the other passage communicateswith the interior of the container through.perforationsfor. other openings in themanifold casing. r 1

These two passages are connected by means: I, of a port or opening through the lamella. The lamella may'be fiatthroughout'its length or curved at the end adjacent the discharge port. 7 to meet the side of the casing, or curved. atboth ends, and the opening. through the lamella may be at the end opposite from the discharge portv or at an intermediate point. Suitable manifolds of several types embodying various combinations of the above-mentioned and other features are 14 and 572,918.

While I may use any of the previously described manifolds in my present container, one of the,

features of the presentinvention is an improved'145 'manifold which is adapted to use with thisor;

other dispensing containers. This manifold 15 is rectangular, as shown in Figs. 4 and 7, and-its, middle lamella 18 is flat and parallel with the;

topand bottom of the l asin -f The manifold is conveniently folded from .a substantially rectangular blank shown in Fig. 5.

This blank is divided into seven parallel sections designated as 17, 18, 19, 20, 21, 22 and 23, as shown. The second section from one end of the blank (section 18 in the'drawings) forms the lamella of the finished manifold, and a' portion of this section is cut out or omitted to form the connecting passage.- One, or preferably two, of

' 2'7 at the other end.

To form a manifold from this blank, the ad jacent sections are folded at right angles, always in the same direction, starting with sections 1'7 and 18, as shownin Figs. 5, 6 and 7. Adjoining sections in the completed manifold, such as sections 1'7 and 21 and/or sections 19- and 23, may

be fastened together in any suitable manner, as p by gluing, stapling, or the like.

- This manifold differs chiefly from one type of manifold described in "my application Serial No.

572,918 in that the perforations 25 are fewer in number and are preferably confined to the front third of the manifold casing, that is, to the third adjacent discharge port 7 in the completed container, and in the provision of one or a few perforations 27 near the rear extremity of the easing. The perforation 2'7 is preferably of the same size or slightly larger than the perforations 25. A These improvements overcome the difficulties which have sometimes been encountered with previously described'manifolds into which too much dust sometimes entered when dusting upward with a full package and not enough dust when the package was more than half empty.

The area of the opening through the middle lamella 18 and the total cross-sectional area of the perforations 25 and 27 should notbe less than the area of the discharge port 7 and may be considerably greater. Each of the perforations 25 and 2'7 should be small enough to prevent the passage of large lumps of material therethrough, however. I

The completed manifold 15 is inserted in side section 1 with one passage covering the discharge port '7, as shown in Fig. 4, and this manifold is fastened in place with glue or the like. Port 9; is punched in section 2, and sections 1 and 2 are hinged together along the edges 3, as previously stated. The sections are then partially closed together by rotation about the hinged edge.

The bellows blank prepared as described here inabove is fastened to thepartially opened side sections 1 and 2, preferably with quick-drying glue. When the glue sets' sufficiently, the side sections and end section of the bellows are pushed in along the center line, giving the bellows the form shown in Figs. 3 and 1. This bellows is simple and strong, especially when provided with reinforcing strips and/or stiffening. It has a single inwardly extending fold on each side and in the preferred embodiment, the side folds are unbroken, giving the bellows maximum strength and durability. e

Before filling, the two sides of the container are brought together in the position shown in Fig. 2. They may then be sealed in this position by means of an adhesive strip of paper or the like, with or without a rip cord, as shown and previously described, or the container may be filled before sealing. The discharge port 7, when in- 1. A, dust-dispensing container .tially horizontal position: 3.
